摘　　要：目的探讨儿童肺隔离症(PS)的CT表现.方法回顾性分析29例经手术病理证实为PS患儿的CT资料,通过多种后处理技术观察病例的影像学特点.采用Fisher确切概率法比较叶内型PS与叶外型PS在分布、供血动脉及引流静脉的差异.结果叶内型PS 21例,CT表现为软组织肿块1例、实变影并周围气肿2例、实变影并周围多发囊腔5例、肺脓肿样表现5例、多发薄壁囊腔并迂曲血管5例、迂曲供血动脉并周围肺组织气肿3例;叶外型PS 8例,CT表现为实性肿块3例、囊实性肿块5例.叶内型与叶外型PS在分布及供血动脉的差异无统计学意义(P>0.05),在引流静脉的差异有统计学意义(P<0.001).结论儿童PS的CT表现多变,可呈软组织肿块、实变影并周围气肿、囊实性肿块、囊性肿块或仅可见异常供血动脉合并肺气肿,平扫可对儿童PS的检出提供重大诊断依据,增强扫描基本可明确诊断.Objective To investigate the CT manifestations of pulmonary sequestration(PS)in children.Methods The CT features of 29 children with PS confirmed by surgery and pathology were observed and analyzed retrospectively by various post-processing techniques.Fisher's exact test was used to compare the dfferences between intralobar and extralobar PS in distribution,feeding artery and draining vein.Results In the 21 cases of intralobar PS,CT showed soft tissue mass in 1 case,consolidation with surrounding emphysema in 2 cases,consolidation with multiple surrounding cystic cavities in 5 cases,pulmonary abscess-like appearance in 5 cases,multiple thin-walled cystic cavities with circuitous vessels in 5 cases and circuitous feeding artery with surrounding emphysema in 3 cases.In the 8 cases of extralobar PS,CT showed solid mass in 3 cases and cystic-solid mass in 5 cases.There were no statistically significant differences in distribution and feeding artery between intralobar and extralobar PS(P>0.05),however there was a significant difference in draining vein(P<0.001).Conclusion The CT manifestations of PS in children are varied,including soft tssue mass,consolidation with surrounding emphysema,cystic-solid mass,cystic mass or abnormal feeding artery with emphysema only.Plain CT can provide important diagnosis for PS in children,and enhanced CT can provide the definite diagnosis mainly.
